Power outlet with a support platform with inclined surfaces with through holes and a shutter with an incline with a hole

Abstract

A power outlet having a base, a top cover, a safety shutter, and an elastic member is disclosed. The base may include a support platform having a first electrode and a second electrode. The top cover may include a first receptacle and a second receptacle and overlaying the base. When in a first position, the safety shutter may be placed at a fulcrum of the support platform with equilibrium and mask the first electrode and the second electrode. The safety shutter may include a first incline and a second incline. When a foreign object invades either the first receptacle or the second receptacle, the safety shutter may lose its equilibrium despite still masking the first electrode and the second electrode. Only after the corresponding plug pins have been inserted into the receptacles before the safety shutter may be pushed away from the first position.

What is claimed is: 
     
       1. A power outlet, which is pluggable and engaged by a power plug having at least two plug pins, comprising:
 a base including a support platform having a first electrode, a second electrode, and a fulcrum between the first electrode and the second electrode are placed, the support platform being a surface above the first electrode and the second electrode and having a right incline and a left incline, the left incline having a first through hole in communication with the first electrode, the right incline having a second through hole in communication with the second electrode, the left incline and the right incline on two sides of the fulcrum, the fulcrum located at a highest position of a connection adjoining the right incline and the left incline; 
 a safety shutter capable of sliding on the support platform and swinging with respect to the fulcrum, when in a first position the safety shutter locating at the fulcrum with equilibrium and masking the first electrode and the second electrode, the safety shutter including a first incline and a second incline, a first side of the second incline having a first punch-through hole, the plug pins being in connection with the first incline and the second incline, and the first incline and the second incline pushing the safety shutter away from the first position to a second position; 
 a top cover having one side in proximity of a second side of the first incline and the second incline and a first receptacle corresponding to the first electrode and a second receptacle corresponding to the second electrode, and the top cover overlaying the base with the safety shutter between the top cover and the base; and 
 an elastic member, one end of the elastic member in contact with the safety shutter, for maintaining the safety shutter at its first position using the elasticity thereof. 
 
     
     
       2. The power outlet according to  claim 1 , wherein when in the first position either the first incline or the second incline of the safety shutter is positioned to be contacted by at least one of the plug pins of the power plug. 
     
     
       3. The power outlet according to  claim 1 , wherein when in the first position the first incline of the safety shutter is positioned to be contacted by at least one of plug pins, which causes the first incline to push the safety shutter to the second position while enabling the second incline to be contacted by another plug pin. 
     
     
       4. The power outlet according to  claim 1 , wherein a center of the first incline is formed with a cavity corresponding to at least one of the plug pins of the safety shutter. 
     
     
       5. The power outlet according to  claim 1 , wherein an inner surface of the top cover is formed with a third incline corresponding to the right incline of the safety shutter and a recess corresponding to the left incline of the safety shutter, the third incline and the right incline tilting symmetrically with respect to a direction along which the safety shutter slides, the safety shutter equipped with a protruding block in the proximity of the first incline, and the protruding block sliding within the groove, which restrains the protruding block when the safety shutter is pushed to the second position.
